The date that changes your book
What is here is the difference between the book you have been using and the one that governs from that date. Not a course, not a summary. The deltas, with the section numbers, so you can check any of them in your own copy. The book check starts from whichever edition you are carrying.

The Commission voted on 28 July 2026 to adopt from 1 September, and Texas kept a GFCI exception the national code retires.

Thirteen article numbers your 2023 book does not have, what each one covers, and where it came from.
- NEC Change Markers: What They Show and What They Miss
The four symbols NFPA marks a new edition with, and its own note that a rearrangement might not be captured.
- Grounding and Bonding in the 2026 NEC: What to Re-read

- How the 2026 NEC Rebuilt the Limited-Energy Articles
Articles 721, 723 and 742 are new, 720 and 750 kept their numbers and changed subject, and Article 770 is gone.
- Motors in the 2026 NEC: Article 430 and the New 430.132
Article 430 kept its sizing method and gained 430.132, which bars GFCI protection between a drive output and the motor.
- NEC Article 750 in 2026 - A Reused Number, New Subject
Article 750 is grounding and bonding of limited-energy systems now. Energy management moved to Article 130.
The three things worth ten minutes
- Article 220 is now Article 120. Every tab and every memorized citation points at the wrong chapter.
- The general lighting figure split rather than changed. Branch circuits and services now use different numbers.
- Amendments issued after publication change the code without changing any printed page. Article 430 gained an entire new section that way.
How it works
- Name the book on your truck. The book check takes the edition you carry and shows what moved, what was renumbered, and which numbers now hold a different rule. Free, and it needs no account.
- Test yourself on ten numbers. Did it move? names a 2023 section and asks where that rule sits in the 2026 book now. A round is ten numbers, drawn from the rows that are free, with the crosswalk row shown after each answer.
- Open the rest of the crosswalk if you want it. Fourteen of the fifty rows are free with their sources. $29 once opens the other 36, each with where the rule sits now, what took over the number you left behind, how sure we are, and the document it was read in with the date.
- See a moved rule in the thing it governs. The switch connection rules that left Article 404 are the clearest case, and the exam site has four hands-on labs where you wire a three way, fill a box, bend a pipe or build a grounding electrode system and the checker names the 2026 section behind each fault. Free, and no account.
Written for people who already know the trade
This site is not exam prep and it is not a licensing guide. It assumes you are licensed and working, and that what you need is what moved since the last edition.
Every claim points at a section number so you can check it in about a minute. Nothing here asks to be taken on authority.
What this deliberately is not
It is not a searchable code database and it will not become one. Section numbers are cited. The code text you read in your own copy.
That line is on purpose. The copy you read the text in is the copy you'll be held to on the job, and it should be the one open in front of you.
When it applies in Texas
Texas adopts the 2026 edition effective September 1, 2026 (16 TAC 73.100).
That is an adoption date, not a switch. Work permitted under the previous edition is generally judged by the previous edition, and local amendments govern locally where they exist.
